Returns the netmask address of ifaddr. nil is returned if netmask is not available in ifaddr.

returns the socket option data as a string.

p Socket::Option.new(:INET6, :IPV6, :RECVPKTINFO, [1].pack("i!")).data
#=> "\x01\x00\x00\x00"

Logs a message at the fatal (syslog err) log level, or logs the message returned from the block.

Compresses the given string. Valid values of level are Zlib::NO_COMPRESSION, Zlib::BEST_SPEED, Zlib::BEST_COMPRESSION, Zlib::DEFAULT_COMPRESSION, or an integer from 0 to 9.

This method is almost equivalent to the following code:

def deflate(string, level)
  z = Zlib::Deflate.new(level)
  dst = z.deflate(string, Zlib::FINISH)
  z.close
  dst
end

See also Zlib.inflate

Inputs string into the deflate stream and returns the output from the stream. On calling this method, both the input and the output buffers of the stream are flushed. If string is nil, this method finishes the stream, just like Zlib::ZStream#finish.

If a block is given consecutive deflated chunks from the string are yielded to the block and nil is returned.

The flush parameter specifies the flush mode. The following constants may be used:

Zlib::NO_FLUSH

The default

Zlib::SYNC_FLUSH

Flushes the output to a byte boundary

Zlib::FULL_FLUSH

SYNC_FLUSH + resets the compression state

Zlib::FINISH

Pending input is processed, pending output is flushed.

See the constants for further description.

Decompresses string. Raises a Zlib::NeedDict exception if a preset dictionary is needed for decompression.

This method is almost equivalent to the following code:

def inflate(string)
  zstream = Zlib::Inflate.new
  buf = zstream.inflate(string)
  zstream.finish
  zstream.close
  buf
end

See also Zlib.deflate

Inputs deflate_string into the inflate stream and returns the output from the stream. Calling this method, both the input and the output buffer of the stream are flushed. If string is nil, this method finishes the stream, just like Zlib::ZStream#finish.

If a block is given consecutive inflated chunks from the deflate_string are yielded to the block and nil is returned.

Raises a Zlib::NeedDict exception if a preset dictionary is needed to decompress. Set the dictionary by Zlib::Inflate#set_dictionary and then call this method again with an empty string to flush the stream:

inflater = Zlib::Inflate.new

begin
  out = inflater.inflate compressed
rescue Zlib::NeedDict
  # ensure the dictionary matches the stream's required dictionary
  raise unless inflater.adler == Zlib.adler32(dictionary)

  inflater.set_dictionary dictionary
  inflater.inflate ''
end

# ...

inflater.close

Returns the last access time for this file as an object of class Time.

File.stat("testfile").atime   #=> Wed Dec 31 18:00:00 CST 1969

Returns true if the file is a character device, false if it isn’t or if the operating system doesn’t support this feature.

File.stat("/dev/tty").chardev?   #=> true

Iterates over keys and objects in a weakly referenced object

Returns the path of this instruction sequence.

<compiled> if the iseq was evaluated from a string.

For example, using irb:

iseq = RubyVM::InstructionSequence.compile('num = 1 + 2')
#=> <RubyVM::InstructionSequence:<compiled>@<compiled>>
iseq.path
#=> "<compiled>"

Using ::compile_file:

# /tmp/method.rb
def hello
  puts "hello, world"
end

# in irb
> iseq = RubyVM::InstructionSequence.compile_file('/tmp/method.rb')
> iseq.path #=> /tmp/method.rb

The platform this gem runs on.

This is usually Gem::Platform::RUBY or Gem::Platform::CURRENT.

Most gems contain pure Ruby code; they should simply leave the default value in place. Some gems contain C (or other) code to be compiled into a Ruby “extension”. The gem should leave the default value in place unless the code will only compile on a certain type of system. Some gems consist of pre-compiled code (“binary gems”). It’s especially important that they set the platform attribute appropriately. A shortcut is to set the platform to Gem::Platform::CURRENT, which will cause the gem builder to set the platform to the appropriate value for the system on which the build is being performed.

If this attribute is set to a non-default value, it will be included in the filename of the gem when it is built such as: nokogiri-1.6.0-x86-mingw32.gem

Usage:

spec.platform = Gem::Platform.local

Enumerate every known spec. See ::dirs= and ::add_spec to set the list of specs.

Return a list of all outdated local gem names. This method is HEAVY as it must go fetch specifications from the server.

Use outdated_and_latest_version if you wish to retrieve the latest remote version as well.

Activate this spec, registering it as a loaded spec and adding it’s lib paths to $LOAD_PATH. Returns true if the spec was activated, false if it was previously activated. Freaks out if there are conflicts upon activation.

Abbreviate the spec for downloading. Abbreviated specs are only used for searching, downloading and related activities and do not need deployment specific information (e.g. list of files). So we abbreviate the spec, making it much smaller for quicker downloads.

The date this gem was created.

If SOURCE_DATE_EPOCH is set as an environment variable, use that to support reproducible builds; otherwise, default to the current UTC date.

The date this gem was created

DO NOT set this, it is set automatically when the gem is packaged.

Normalize the list of files so that:

• All file lists have redundancies removed.

• Files referenced in the extra_rdoc_files are included in the package file list.
